Used primarily as a highly stable inert fluid in specialized industrial and laboratory applications. Its extreme chemical and thermal stability make it suitable for use in oxygen-rich environments, such as in aerospace and medical devices, where resistance to combustion is critical. Commonly found in electronic testing as a heat transfer medium due to excellent dielectric properties. Also utilized in perfluorocarbon-based oxygen carriers and biomedical research for cell culture and organ preservation. Its non-wetting and non-reactive nature supports use in precision cleaning and coating processes, especially in semiconductor manufacturing.
